2012 Nissan Leaf: what breaks, and at what mileage

What breaks on the 2012 Nissan Leaf

On the 2012 Nissan Leaf, the failure owners report most often is other brake problem, and the reports cluster around 20,000 miles. The earliest to appear is other electrical problem, reported by a median of 10,000 miles. Overall it scores 70 out of 100, high risk for a 2012.

High risk for a 2012 — 156th riskiest of the 271 2012 vehicles we can rate. 71 owner reports; fleet size borrowed from other years of the same model.

What breaks on the 2012 Nissan Leaf

Owners have reported 18 named failure modes on the 2012 Nissan Leaf, and the three most-reported carry 49% of everything filed.

Other brake problem leads with 18 reports, about 0.8 per 1,000 vehicles and with the middle half of reports between 8k to 25,000 miles.

Other electrical problem follows with 13 reports, usually reported between 7k to 20,000 miles.

Other body or interior problem follows with 4 reports, median 20,000 miles.

By system, the reports fall mostly into brakes (21), electrical (13) and body (5).

At what mileage it happens

51 of the reports on the 2012 Nissan Leaf came with an odometer reading, and half of those were filed before 15,000 miles.

Cumulatively, 86% by 50,000 miles of the dated reports had been filed.

The busiest stretch is between 0 and 10,000 miles, which alone holds 37% of the dated reports.

76% of the dated reports were filed below 36,000 miles, which is early enough that a fair number of these cars were still under a factory warranty when the owner complained.

Severity, and what it costs

Across the named modes, 9 mention a crash and 3 an injury. Those are the words owners used in their own complaints, and NHTSA does not verify them, but they are the closest thing in this data to a measure of what a failure actually did.

The average severity weight across every report on this year is 4.06, where a stalled engine or a failed airbag weighs many times more than a rattling trim panel, and a figure this high means the reports are dominated by failures with safety consequences rather than annoyances. The weighting is set out in full on the methodology page.

What the top failures cost to put right, as editorial estimates for an independent US shop rather than figures from NHTSA: other brake problem at $300–$1,800, other electrical problem at $250–$2,000, other body or interior problem at $200–$2,000 and other speed control problem at $250–$2,000. Dealer labour, a seized bolt or a part that is no longer made can push any of these past the top of its range.

4% of the reports on this year sit in the engine, transmission, drivetrain or cooling systems — the four where a repair bill is usually four figures.

This year had no usable recall paperwork, so the fleet-size estimate is the median of other years of the same model. Repair costs are typical independent-shop ranges for the failure, not figures from these reports.

How often, against how many were built

Scaled by an estimate of how many of these cars exist, the 2012 Nissan Leaf draws about 3.1 per 1,000 vehicles, which puts it in the 83rd percentile of complaint rates among 2012 vehicles we can rate.

That denominator is the weakest number on the page and it is fair to say so plainly. This year had no usable recall paperwork, so the fleet-size estimate is the median of other years of the same model.

The working figure is 22,791 vehicles. If the true number is twice that, every rate on this page is half what it says; the ranking against other 2012 vehicles, which is what the risk score uses, is far more robust than the rate itself.

Other brake problem

I was traveling at highway speed. The car in front of me began a fast reduction in speed. I rapidly applied my brakes to the point of full stopping power. Shortly afterward I released the brake as I was confident I would not hit the car in front of me. The brakes kept their full stopping force for at least another 1/2 to 1 second. I had to steer off the road to prevent the car behind from hitting me. This has happened twice before but I did not record all the details until today. This is twice now that I had to make a medium speed emergency dive off the highway to avoid immediate collision from the rear. In my first incident I was traveling 70 MPH on i25. This is frightful dangerous braking behavior. I love my leaf but in my opinion this automobile is not safe to drive on a freeway. I called the dealer and will take the car in tomorrow but I was told there are no nissan notes on this failure mode. *tr

6,600 miles NHTSA complaint 989901 filed 2013-06-28

Driving my 2012 leaf on a secondary road on sunday afternoon, at 45 MPH, I applied my brakes to turn right on to another street. After moderately pressing the brake pedal the brakes locked, bringing the vehicle to a complete stop in the roadway. My foot had not been on the brake pedal for at least a full second while my vehicle continued to abruptly stop. A vehicle behind me rear-ended the leaf. I and my two passengers received neck injuries. This is absolutely a defect in the braking system that needs to be resolved. I consider nissan at fault and not the driver of the vehicle that rear ended us. *tr

Other electrical problem

Tl* the contact owns a 2012 nissan leaf. The contact stated that while driving approximately 35 MPH in eco- mode, she noticed the battery mileage count suddenly decreased from 77 miles to 55 miles after driving approximately a mile. The contact stated after charging the vehicle overnight, the battery did not completely charge. The vehicle was taken to the dealer for diagnostic testing. The technician stated there was not a failure. The vehicle was not repaired. The approximate failure mileage was 70.

Car does not drive the number of miles the electric charge states and dealership reports. The vehicle is dangerous cause to drive at posted speed limits of major highways the charge is used up very quickly like 3 times whatever speed you are driving if over 50 MPH. *tr

Other body or interior problem

Page 1-21 of the 2012 nissan leaf owner manual has an illustration of a forward-facing convertible child restraint incorrectly installed, with the caption "latch webbing-mounted attachment". The illustration shows the forward-facing convertible child restraint installed with the lower anchorage flexible connector strap (latch webbing) routed through the rear-facing child restraint belt path. No webbing is routed through the forward-facing child restraint belt path. This illustration may suggest to users that this is how to route the "latch webbing" in a forward-facing child restraint illustration, which may lead to injury. This illustration is common to many models of 2003 and later nissan vehicles, not just the leaf. *tr

50 miles NHTSA complaint 1017273 filed 2013-10-22

New car headrests are angled too far forward. I do not want to slouch, so I would like to sit with my seat upright. This forces my head into a very unnatural position, causing me pain. Even with the seat tilted back, the headrest still forces my head forward, and creates a difficult driving position with my shoulders slumped forward and my head tilted. This causes headaches & distraction. This discomfort is also true of the 2013 ford focus, the 2010 toyota prius, and the 2013 subaru outback that I have recently driven. I understand this is an effort to reduce whiplash injuries, but it is causing flexion/overuse injuries in owner's necks!

How it ranks in the 2012 field

The score at the top of the page, placed among its peers. The zones are the same thresholds the scorer applies, read out of the scorer itself, so the picture and the band word cannot disagree.

Risk score against the rest of the 2012 field

Scores are ranked within the model year, never across years, because an older car has had longer to accumulate reports.

  • Left fewer and less serious reports
  • Right more, or worse
  • Marker this vehicle

Where 2012 sits in the model line

High risk for a 2012 — 156th riskiest of the 271 2012 vehicles we can rate. The comparison is always within the same model year, so an older car is never penalised for having had longer to break.

Across the 13 model years of this car that carry enough reports to score, 2011 comes out best at 68 and 2018 worst at 78, with 2012 itself at 70.

No other year of this model scores meaningfully better than 2012, so if this generation is what you want, the year is not the lever.

Within the 2010–2017 generation specifically, 2011 is the strongest year at 68 and 2015 the weakest at 72.

Scores compare each year against other cars of the same model year, so a low number on an older car is a real result and not an artefact of age.

Risk score by model year, out of 100

Shorter is better. Years with too few reports to score are shown without a bar rather than as a zero, because no data is not good news.

Within the 2010-2017 generation, 2011 Nissan Leaf scores best at 68 and 2015 Nissan Leaf worst at 72.

Where to spend the inspection money

The mileages below are where the first quarter of reports for each mode had already been filed, which makes them the point at which a fault is worth looking for rather than the point at which it happens: other electrical problem from about 7k and other brake problem from about 8k.

On a 2012 Nissan Leaf with more miles than that on it, the useful question to put to a seller or a mechanic is whether other electrical problem has been dealt with, and if so with what parts and at whose expense. A car that has already had the repair is in a different position from one that has not.

None of this is a diagnosis. It is a list of what other owners of the same model year reported, ordered by when they reported it, which is a good place to point an inspection and a poor place to stop.

What this page cannot tell you

71 owner reports; fleet size borrowed from other years of the same model. Every count on this page is therefore a floor: it is the number of owners who went to the trouble of filing with a federal agency, which is a small and self-selected fraction of the owners who had the fault.

Of those 71 reports, 51 carried an odometer reading, so the mileages here describe 72% of the sample rather than all of it. Owners also round: readings pile up on multiples of ten thousand, which is why this site publishes "about 90,000 miles" and not "91,438".

Named failure modes come from matching phrases in the complaint text, so a badly worded complaint can land in the wrong bucket. The effect washes out across hundreds of reports and does not wash out across five.

And nothing here predicts what one car will do. These are other people's complaints, filed years apart, on cars maintained by strangers. Read the page as a map of where this model year has previously gone wrong, then have the specific car in front of you inspected.

Questions this page answers

What are the most common problems with the 2012 Nissan Leaf?

The most-reported failures are other brake problem (18 reports, median 20,000 miles), other electrical problem (13 reports, median 10,000 miles) and other body or interior problem (4 reports, median 20,000 miles). Counts come from owner complaints filed with NHTSA, which are voluntary, so they show what owners bothered to report rather than every fault that occurred.

At what mileage do 2012 Nissan Leaf problems start?

Other electrical problem is the earliest failure mode to show up, with a median reported mileage of 10,000 miles and a quarter of reports before 5,000 miles. Across all failure modes on this year, the median report sits at 15,000 miles.

Is the 2012 Nissan Leaf reliable?

It scores 70 out of 100 on our risk index, which is high — 156th riskiest of the 271 2012 vehicles we can rate. The score is a comparison against other 2012 vehicles, not a prediction about any individual car, and it is built from complaint rates, severity and how early failures appear.

Which year of the Nissan Leaf is best?

Within the 2010–2017 generation, 2011 scores best at 68 out of 100 and 2015 worst at 72. Same body, same engines, different luck.

Where this comes from. Every figure above is computed from NHTSA owner complaints and recall records for this exact make, model and year. Complaints are voluntary and self-selected, so treat counts as a floor. The methodology page writes out each formula, and the same numbers are available as JSON.
